Mechanisms of biodegradation of dibenzoate plasticizers
The biodegradation of the commercial plasticizers D(EG)DB and D(PG)DB by the yeast, R. rubra, resulted in the formation of substantial amounts of the metabolites, diethylene glycol monobenzoate (D(EG)MB) or dipropylene glycol monobenzoate (D(PG)MB) (Gartshore et al., 2003). These monoesters were shown to be toxic and, especially in the case of
Mechanisms of biodegradation of dibenzoate plasticizers
Biodegradation mechanisms were elucidated for three dibenzoate plasticizers: diethylene glycol dibenzoate (D(EG)DB), dipropylene glycol dibenzoate (D(PG)DB), both of which are commercially available, and 1,6-hexanediol dibenzoate, a potential green plasticizer.

New Dibenzoate Plasticizer Blends for PVC Applications
Dibenzoates plasticizers are well-established and are used in PVC applications. Chemically, these plasticizers are non-phthalates and function well as high-solvating. In the past, new...
Benzoates / Dibenzoates - Plasticisers - Information Center
Dibenzoates are made by the reaction of diols like diethylene glyol, triethylene glycol or dipropylene glycol with benzoic acid. Benzoates are in general fast fusing plasticisers offering complemetary performances to general purpose plasticisers. Monobenzoates also work as low VOC and low viscosity agents for PVC plastisols.
- What is a dibenzoate plasticizer?
- Dibenzoate plasticizers are highly solvating monomeric plasticizers that decrease processing times and lower processing temperatures. In addition, they offer superior resistance to extraction by solvents such as kerosene, cotton seed oil and soapy water.
- Is diethylene glycol dibenzoate toxic?
- The U.S. EPA High Production Volume Information System (HPVIS 2009) lists both diethylene glycol dibenzoate (DEGDB) and dipropylene glycol dibenzoate (DPGDB) as non-mutanogenic and non-carcinogenic. Furthermore, the ECHA 2009 assessment lists DPGDB as not persistent, not bioaccumulative and not toxic, making it a “non-PBT” material.
- Are there alternative plasticizers?
- There are a considerable number of alternative plasticizers in employment, without any toxicological data available (dibutyl adipate, diethylene glycol dibenzoate, and bis-2-ethylhexyl sebacate, to name a few).
- Are dibenzoate plasticizers better than phthalates?
- From a health and environmental perspective, the European Chemical Agency (ECHA) listed dibenzoate plasticizers as a preferred alternative to phthalates in May 2009. Certain grades of dibenzoate plasticizers are more environmentally friendly than others. Many require no warning labels and are even approved by the FDA for use in food packaging.
- Which polymers are compatible with dibenzoate plasticizers?
- Compatibility with a variety of polymers and applications. Dibenzoate plasticizers are compatible with many polymeric materials, including ethylene vinyl acetate (EVA), polyvinyl chloride (PVC), styrene-butadiene rubber (SBR), ethyl cellulose (EC), nitro cellulose (CN), cellulose acetate butyrate (CAB), polyurethane (PU) and acrylics (PMMA).
- Are dibenzoate plasticizers safe?
- Dibenzoate plasticizers are an attractive option. Unlike some newer alternatives, such as diisononyl cyclohexane-1,2-dicarboxylate (DINCH), dibenzoate plasticizers have a proven track record of performing safely and reliably. They have been in use for a variety of applications worldwide for more than 40 years.
